more convenient member of this nature and 1 for the, purpose stated. f

My invention relates more particularly to a safety razor blade utilityknife member which is so-constructed as to provide a relatively thin`and small Ivest pocket article, of light weight, easily adjustable fromcarrying position to working position and vice versa,

and which is convenient to carry in the closed y position'and soextended in its working posipermit easy handling thereof and knife quitesuitable for general a relatively dat case for housing a blade holderwhich in turn is adapted-to support the blade. The holder is slidablewithin `the case to and from the carrying and working positions and theconstruction is such that the parts, including the guiding and retainmgelements'between the case and holder, may be most convenientlyandeconomically stamped from sheet metal'. The production of such animproved device of this nature and for the 'purpose stated comprises afurther object of my invention.

In the accompanyin' drawings I have illustrated one specific em odimentof my invention but it will be understood that the invention, can beotherwise embodied and that the drawings are not to be construed as'definite or limiting the scope of 'the invention, the claims appendedhereto being relied upon for that purpose.4

Referring now to the embodiment of my (it)I invention which isillustrated in the accompanying drawings,- 10 designates a case withinwhich is`slidably mounted a holder 12 adapted to receive and carry asafety razor blade 14. While the case andl holder may be constructed invarious forms and by various methods, they are capable of very i simpleand economical construction and I have preferred to' herein illustratethe same as thus made, preferably of sheet metal and b v well knownstamping operations;v Thus, while I shall now proceed to dene thespecific construction illustrated, it will be understood that the sameisby no means to be construed as a limitation on the invention.

The case 10, as illustrated, is formed from a flat sheet, referably ofmetaLIben-t yU- 'shaped upon itself to provide two iiat and relativelybroad-sides connected together at an edge 16. One end and aportion ofone side edge' of the'case is substantially closed by inwardly turnedflanges 18 and a bail 20 for lattachino` a chain may beV connected tothis end. The other end of thecase and the adjacent longitudinal/ edgeportions opposite the closed edge 16 are open for permitting the passa eofthe holder 12.

The ho der 12 is likewise formed from a flat sheetl bent U-shaped uponitself to provide two side portions for securing and holding the blade14 therebetween. The connecting edge of the holder is relatively wide inthe nature 'of abead 22, whereby an outward orflaring effect of theholder sides may be provided, and the co-operating portion 24 of thecase adjacent to its edge 16 1s likewise relatively wide whereby-toreceive the bead `and permit longitudinal and'transverse movenient ofthe` holder: withinl the case. The

sides of the case outwardv of the portion 24 are parallel and engageatwise against the side portions of the'holder. y

The closed and open positions of the holder within the case are shown inFigs. 1 and 3 respectively, the holder being movable diagonally of thecase longitudinally and edgewise through an open end and side thereof toand from these positions. Thismovement isfacilitated and the holder isguided and held securely relatively to the case by a co-operatingguiding connection between adjacent sides of the case and holderelements. As illustrated, the guides of this connection are preferablyintegral with these elements and may comprise co-oplerating-dia onalldisposed ribs stamped t erefrom. he ri 2610i the case is shown pressedoutwardly in groove-like form and the rib 13 of theholder 12 is pressedoutward and is slidable longitudinally in the rib 2,6.' Said .ribsretain the case and the holder in different positions of said parts..Stops 26a are shown located at the ends of the groove of rib'26, saidstops being in the path of rib 13 to be engaged thereb to limit thelongitudinal movement of t e holder within the case.

The holder may be drawn outwardly* byiv grasping a linger piece 28 andmay be retained in two positions by a releasable detent l comprising. aresilient button 30 carried by the holder and engageable within tworelatively spaced o enlngs 32 and 32a in one side of the case. en theholder is in its extended position, Sig. 3)', the blade edge is exposedfor use yond the case. The co-operation of the ribs in conjunction withthe diagonal or inclined positions thereofv resist thrusts against theblade edge in use. i When the holder is pushed inwardly in the case theblade edge will be concealed Vand shielded by the case, as in Fig. 1.

As shown in Fig. 7, the button 30isl an integral part of the inwardlyextended end portlon of the side 15 of the holder. The adjacent end ofthe other side 15a of the holder is attached to the lside 15 by means of'a ange 36 thereon entering a slot formed in the said side 15. The outeredge portions of the side portions ofthe holder normally spread apart orflare, as shown in Fig. 5, an

when in said position with the holder drawn outwardly as in Fig. 3, theblade can be removed and another inserted, the side portions beingnotched at 38 for assisting this operation. These edge portions of thehold-v er are held clamped against the blade by the finger pieceor`gripper 28shown as a U- shaped member engaged over the outer end andthe adjacent side portions of the holder. The gripper 28 is heldinsliding position on the holder by means of a retaining linger 40struck out therefrom and extending through aligned slots 42 in the sideportions of the holder. The gripper member 28 older 12 release the bladeto facilitate removal and replacement. The case also may be notched at44. s

Y The inner end of the holder side 15 can be sharpened and used as cigarcutter, taking advantage of the aperture 32 to receive the Y cigar end,(Fig. 7).

The parts as illustrated are simple but substantial and the arrangementis such that the device can bel made economically and will serve Aitsintended function with great facility.
